Be it known that I, BENJAMIN F. FAUNcr,

-' a 'citizen of the United States, residingat a specification.

"lohnstown, I have invented certain new and useful Im- Cambri'a county, Pennsylvania,

proveinents in Adjustable Mills for Rolling Circular Sections, of which the following is This invention relates to millsfor rolling various circular sections such as steel car wheels,'large gears, pulleys etc., andis an art from the following description when read in connection with the accompanying drawings in which:

Figure 1 is a plan view partly in horizontal section;

Fig. 2 is a side elevation thereof;

Fig. 3 is a transverse section on the 3-8 of Fig. 1;

Fig. 4 is a transverse Moi Fig. 1;

Fig. 5 is a detail view of my improved form oi spacer.

Referring to the drawings 10 represents a supporting structure on which carriages line section on the line 11 and 12 are guided in the ways 13 and 14 formed thereon. Ihe carriages 11 and 12 form adjustable supports for the complementary forming dies 15 and 16. ihese dies being carried by holders'17 and 18 having suitable thrufst bearings and 20 coopcrating therewith to minimize thefriction on the bearings thereof during the rolling;

or i'orgingoperation. v

The dies are rotated by shafts and 22 from any suitable source of power. In normal operation the carriage 12 is held in a fixed position so that the workingface of the die 15 does not move in the direction of its axis. The carriage 11 provided with suitable Ipeans whereby it is moved axially to exert a pressure on the work W supported therein.

in former constructions machines of this typehave been so designedand. built that Specification of Letters Patent.

the holder for the fixed die was supported in stationary bearings. With such a construction when it was necessary to adjust the die 15 in axial direction to'compensate for the W631 thereon, it 'was necessary to either remove sald die and substitute a new one or to insert liners or spacers between K it and its holder to correctly position its v This was a rather pri'mitive way of adjusting the position'of the die and in practice proved to be a slow and inefficient way of making theadjustment.

In the embodiment of my invention herein shown, the diel5 and holder 17 thereof are mounted on the carriage-11 which being slidably supported in the ways 13'permits v of'an axial movement whereby the wear on the working face of the die may be readily mounted on the supporting structure are adapted to move the carriage 11 in a ,direction parallel with the axis of the holders An abutment 24 is' secured-to the supporting strubture 10 for limiting the backward movement of the carriagg 11 and this abutment carries a pairof. outwardly ex- I tending bars25 which support the spacers 26 which tween the rear of the carriage Y11 and the said abutment 2 1 in order to vary the position of they working face'of the die 15.

These spacers have hooks 27 formed thereon for engagement with the rods 25 and are slotted at 28 to enable their being readily slipped over the shaft 21 which drives the die 15. The spacers 27 as shown clearly in Fig. 1, are of varying thickness and by their use the working, face of the die 15 can initially be very accurately adjusted, and as the die wears after use, one or more spacers of different thicknesses may beinterposed or substituted for the ones carried by the pins 25 to compensate for the wear on the die 15. y

Though I have described with great particularity details of construction of the specific embodiment herein shown, it is not to be construed therefrom that I am limited thereto as changes in construction and sub stitution of mechanical equivalents maybe made by those skilled in the art without departin from the invention as defined in the appen ed claims. I What I claim is: 1. In a mill for rolling circular sections carriages having rotatable dies mounte are adapted to be interposed be-- therein, whose axes extend at an oblique angle to each other, one of said carriages" being normally held in a fixed position and the other being mounted so as to permit of movement toward the oppositex carriage obliquely to the axis of the die mounted therein, a supporting structure for saidcarriages and detachable spacers interposed be-- tween'an abutment on said supporting structureand the fixed carriage, said spacers be-- ing adapted to permit substitution of other spacers to compensatefor the wear on the the Working face of the die mounted therein. v

3. In a mill for rolling circular sections,

carriages having rotatable dies mountedt'herein, one of said carriages being normally held in a fixed position, and the other being mounted so as to permit of movement toward the opposite carriage, a supporting structure having an abutment thereon for said fixed carriage, spacers interposed be tween said carriage and said abutment to" position the working face of the die carried thereby, and means'carried ,by said abutment for supporting said spacers.
